Blood flow causes alterations of the NMR-Signal. Cross-sections of vessels will sometimes be imaged as dark spots, sometimes as highlighted areas. These highlightings of the lumen of vessels are often interpreted as caused by obstruction. In this paper the mechanisms of signal-intensity alterations as caused by blood flow will be described in order to prevent errors in interpreting of NMR-Images. The results of flow-measurements with the 0.35 Tesla imaging system in Berlin will also be presented. Finally, clinical examples of flow influence on images will be discussed.
血流会导致核磁共振信号发生改变。血管的横截面有时会成像为黑点，有时则成像为高亮区域。血管腔的这些高亮现象常被解释为是由阻塞引起的。在本文中，将描述由血流引起的信号强度改变的机制，以防止在解释核磁共振图像时出现错误。还将展示在柏林使用0.35特斯拉成像系统进行血流测量的结果。最后，将讨论血流对图像影响的临床实例。
